when does an 11B get their blue rope in the army

An 11B gets the blue cord after completing infantry training—typically at the end of Infantry OSUT, or at the “Turning Blue” ceremony right before graduation. For enlisted infantry soldiers, that’s usually after the full 22-week Infantry One Station Unit Training program, and it’s also tied to being in an infantry-qualified assignment.

What that means

• If you’re talking about a brand-new 11B, the cord is awarded once they finish Infantry OSUT and are officially recognized as infantry-qualified.

• If someone comes through split training instead of OSUT, they get it after completing infantry AIT requirements.

• The blue cord is not just for having the MOS; wear also depends on being in an authorized infantry assignment.

Practical answer

So the short version is: they get it at the end of training, not when they first become 11B. The ceremony is usually the day before graduation, which is why you’ll hear people call it “Turning Blue”.

Quick note

If you meant a soldier who was already 11B, left infantry, and later returned, the cord can depend on current duty position and authorization, not just the MOS itself.
